'wet bulb temperature'

A whirling psychrometer is a device used to measure the relative humidity of the air. It consists of two thermometers: a dry-bulb thermometer and a wet-bulb thermometer. The dry-bulb thermometer measures the ambient air temperature, while the wet-bulb thermometer measures the temperature of a wetted wick as air passes over it. Here's how a whirling psychrometer works: Wet the wick of the wet-bulb thermometer with distilled water. Attach the dry-bulb and wet-bulb thermometers side by side on a handle or a frame. Rapidly spin the psychrometer in the air for a few minutes. This spinning motion helps evaporate water from the wetted wick, causing the wet-bulb temperature to drop. After spinning, observe and record the temperature readings from both thermometers. The difference between the dry-bulb and wet-bulb temperatures is used to calculate the relative humidity of the air using a psychrometric chart or equation. The evaporation of water from the wet-bulb thermometer causes the temperature to decrease, and the rate of evaporation is influenced by the humidity of the surrounding air. The lower the relative humidity, the greater the evaporation and the greater the temperature difference between the dry-bulb and wet-bulb thermometers. By using the psychrometric chart or equation, the temperature readings from the whirling psychrometer can be used to determine the relative humidity, dew point temperature, and other properties of the air. This information is valuable in various applications, such as weather forecasting, HVAC systems, and industrial processes where humidity control is important.

# Submersible LED Fountain Lights: Why Quality Matters in Underwater Illumination When it comes to transforming water features from daytime attractions into nighttime spectacles, submersible LED lights play an indispensable role. At Ekjan Associates, we understand that the magic of illuminated fountains, ponds, and water features depends entirely on the quality of lighting components chosen. Today, we explore why investing in premium submersible LED lights, like our IC Series, makes all the difference in creating stunning, reliable underwater illumination. ## The Unforgiving Nature of Underwater Environments Water creates one of the most challenging environments for electrical equipment. Submersible lights must withstand constant immersion while maintaining electrical safety and optical performance. This demanding environment reveals the true quality difference between premium and budget lighting solutions. ### The Water Challenge: Pressure, Corrosion, and Conductivity Water exerts pressure on sealed enclosures, testing every seal and gasket. Even small imperfections in waterproofing allow moisture penetration, leading to catastrophic failure. Quality lights like our IC Series feature genuine IP68 protection—the highest waterproof rating—ensuring complete submersion safety even at significant depths. Corrosion presents another relentless challenge. Water, particularly when treated with chemicals or containing natural minerals, aggressively attacks metal components. Cheap lights often use inferior materials that corrode rapidly, causing housing failure, electrical shorts, and light degradation within months. Our IC Series utilizes marine-grade stainless steel 316 investment casting—the same material used in harsh marine environments—providing exceptional corrosion resistance that maintains structural integrity for years. Water's conductivity makes electrical safety paramount. Any water ingress into electrical components creates immediate shock hazards and equipment failure. Premium lights employ multiple layers of protection: superior sealing, high-grade cable insulation, and robust connector systems that maintain safety throughout their operational life. ## Why Quality Matters: The True Cost of Cheap Lights ### Premature Failure and Replacement Costs Budget LED lights might offer attractive initial pricing, but their shortened lifespan creates false economy. Cheap lights often fail within 6-12 months of installation, requiring replacement. When you factor in: - Draining water features for access - Labor costs for removal and installation - Repeated equipment purchases - System downtime during repairs The total cost quickly exceeds investing in quality lights initially. Premium lights like our IC Series, built with high-power Cree LEDs and superior components, deliver operational lifespans measured in years, not months. ### Safety Implications Electrical failures in underwater lights present serious safety hazards. Water entering failed housings creates shock risks for anyone contacting the water. Quality lights with genuine IP68 protection and superior construction maintain safety throughout their service life, protecting both users and installers from electrical hazards. ### Performance Degradation Cheap lights suffer rapid performance decline. Water penetration clouds lenses, corrosion darkens reflectors, and inferior LEDs lose brightness quickly. What begins as barely adequate illumination deteriorates into dim, discolored output that ruins the aesthetic appeal of water features. Quality lights maintain consistent color temperature, brightness, and beam characteristics throughout their lifespan, ensuring your water feature looks as impressive in year five as it did at installation. ## The IC Series Advantage: Engineering Excellence Our IC Series submersible LED lights exemplify quality construction designed specifically for demanding underwater applications: ### Premium LED Technology We incorporate high-power Cree LEDs—industry-leading components known for superior brightness, color accuracy, and longevity.
